The history of the US Faction/Federation of the Left Communist International aka the US Bordigists is obscure.
They seem to have started off as a Italian Emigre group in late 1920s, picked up a split of Engish speaking Americans from the Oehlerites in the late 1930s and wound up in the 1950s. In the 1940-50s they published an English language magazine titled "International Bulletin" renamed "Internationalist" in 1949. In his history of the Bordigist Current, Phillipe Bourrinet mentions a second group in Philadelphia.
